Since April 2009, the indoor display products of the company have passed the EMC certification standards of the European Union. In April 2010, the outdoor display products also passed the EMC certification standards of the European Union. It has become the only optoelectronic enterprise in China that has truly passed the EMC certification of the European Union.
The LED standard display of Decolor Optoelectronics mainly solves the electromagnetic interference problem through the special design of the ground wire, circuit board and filter, as well as the structural shielding and overlapping design, and fully meets the CLASS A industrial standard.
With the development of electrical and electronic technology, the popularization and electronicization of household electrical appliances, the development of radio and television, postal and telecommunications, and computer networks, the electromagnetic environment is increasingly complicated and deteriorated, making electromagnetic compatibility (EMC) and electromagnetic interference of electrical and electronic products. (EMI) and electromagnetic immunity (EMS) issues are also receiving increasing attention from governments and manufacturing companies. Electromagnetic compatibility (EMC) of electronic and electrical products is a very important quality indicator. It is not only related to the reliability and safety of the product itself, but also affects the normal operation of other equipment and systems. Protection of the electromagnetic environment.
The full name of EMC (Electromagnetic Compatibility) is EL ectro Magnetic Compatibility, which is defined as "the ability of equipment and systems to function properly in their electromagnetic environment without posing unacceptable electromagnetic disturbances to anything in the environment." The definition includes two aspects. First, the device should be able to work normally under a certain electromagnetic environment, that is, the device should have a certain electromagnetic immunity (EMS); secondly, the electromagnetic disturbance generated by the device itself cannot be Other electronic products have an overwhelming effect, namely electromagnetic interference (EMI).
The European Community (now known as the European Union) government stipulates that from January 1, 1996, all electrical and electronic products must pass EMC certification and be affixed with the CE mark before they can be sold in the European Community market. The move has caused widespread influence in the world, and governments have taken measures to implement mandatory management of EMC performance of electrical and electronic products.
The testing items related to EMC certification standards mainly include: electromagnetic interference (EMI) and electromagnetic immunity (EMS). The indoor (outside) display products certified by Decolor Optoelectronics EMC have passed the following four test standards:
EN 61000-6-4:2007 Standard Electromagnetic Compatibility (EMC). Part 6-4: General Standards. Emission Standards for Industrial Environments (IEC 61000-6-4:2006)
EN 61000-6-2:2005 Standard Electromagnetic Compatibility (EMC). Part 6-2: General Standards. Immunity to industrial environments
EN 61000-3-2:2006 Standard Electromagnetic Compatibility (EMC) --- Part 3-2: Scope---Harmonic radiation (equipment output current ≤ 16A / per phase)
EN 61000-6-3: Electromagnetic compatibility - Part 6-3: General standard. Radiation standard for residential, commercial and light industrial environments
The actual test results of the German (external) display products in German professional EMC testing institutions are 6DB lower than the limits specified by the certification implementation standards.
